I have been entertaining the idea of a 08-09 c63amg for about 8 months now and while searching I've come to find a lot of other options for the same money. I would never buy a new car over 40k just because of the deprecation I find the smell of money more enticing than the "new car smell". I really want a v8 number of doors doesn't really matter. I want to be able to drive long distance and be comfortable which is a feat considering I'm 6'2". The car won't be a daily driver just for weekends and cruising. Any thoughts or suggestions I'm stumped... Maybe i should find the one with the best price and just jump on it, if I hate it sell it with out losing my a88. Another thought, which is going to hold its value the best?

Srt6 (best buy financially I wouldn't have a payment)
Lexus isf
BMW 650i (not great reviews)
Lotus Elise
Jag XF R supercharged coupe
Audi rs4
Ford Mustang Shelby gt500
Corvette z06 (Least favorite but an option)
